Seconding this, after a dozen or so pilots(or different levels of the same pilot), it can get somewhat frustrating to sort through <<
Added a search filter today for the next build. 👍 It can search on name/callsign/mech name/frame/equipped systems+weapons/LL/talents.
Also, have you discovered the folder system for pilots? It’s the button above duplicate on a roster entry. You can put pilots in whatever folders you want and collapse the folders.
